What is happning: cute little puppy part 1

Hi there, my name is Amy Evergreen and my life was normal but that all went away when I met a strange dog, and by strange I mean that the dog could talk, and soon I was saving lives but not as Amy Evergreen but as Sailor Aqua, princess of the water. Now I need to find more team mates to defeat the evil Nexus, who wants to take over the world.

Hiiiiiii, so the cover art is not mine so all credit to the person who made it and this story is not related to Sailor Moon, I was just watching it for the first time so I thought just to... you know what never mind. Anyway, Bu-Bye.
